Hi WG,
I support WG Adoption of this draft. It is a good start and it does make sense to merge these drafts. 1) Does draft-lin-bgp-ls-sr-policy-admin-flags – provide the correct flags to be queried by BGP-LS? Are there some missing? Is this a good start? Are there technical flaws It is a good start. 2) After asking question 1, consider does it still make sense to merge draft-ali-idr-bgp-ls-sr-policy-sl-opt-distribution-00 and draft-lin-bgp-ls-sr-policy-admin-flags-03.txt. Yes. 3) Is there any drafts in the same area that should be considered? No. Thanks , Winnie.

I did not specifically call for an adoption of draft-lin-bgp-ls-sr-policy-admin-flags-03.txt in the call for 3 drafts attached below prior to combining it with draft-ali-idr-bgp-ls-sr-policy-sl-opt-distribution-00.txt. This starts a WG adoption call for draft-lin-bgp-ls-sr-policy-admin-flags-03.txt. The authors should reply to this message with an IPR statement. The WG should consider: 1) Does draft-lin-bgp-ls-sr-policy-admin-flags – provide the correct flags to be queried by BGP-LS? Are there some missing? Is this a good start?

Cheerily, Sue Hares PS – thank you to the IDR chair team and especially Jie Dong our secretary for catching my error.

The authors of these three drafts should respond to this email with an IPR Statement specifying the following: 1) draft you are a co-author on, 2) Whether you know of any IPR on that draft. Background for the WG and Spring. [I-D. draft-ietf-spring-srv6-policy-sid- list-opt] specifies procedures to indicate whether the endpoint's node SID needs to be included or excluded when installing the SRv6 Policy. 1) draft-lin-idr-sr-policy-admin-flags specifies as Segment List Administrative Flags as segment list SubTLV. Flags include: S- admin shutdown, B- backup ineligible, I-Ignore service route's Prefix SID, D- drop upon invalid (section 8.2, RFC9256), and E – eligible. 2) draft-liu-idr-sr-segment-list-optimize<https://urldefense.proofpoint.com/v2/url?u=https-3A__datatracker.ietf.org_doc_draft-2Dliu-2Didr-2Dsr-2Dsegment-2Dlist-2Doptimize_&d=DwMFAg&c=euGZstcaTDllvimEN8b7jXrwqOf-v5A_CdpgnVfiiMM&r=rEoy_H4r-c4UNUr3jSF-7Q&m=RjntOQpE0PTOmyN9aktQ2Swdw2n9KkMaab5dO_bRoNPQbJdQYV5cBJEfNcJbuuOI&s=rwc-kio_SJHar0SdViNs5UMjP6RG_m8-s8v6at9IV5o&e=> <http://draft-liu-idr-sr-segment-list-optimize%3Chttps//urldefense.proofpoint.com/v2/url?u=https-3A__datatracker.ietf.org_doc_draft-2Dliu-2Didr-2Dsr-2Dsegment-2Dlist-2Doptimize_&d=DwMFAg&c=euGZstcaTDllvimEN8b7jXrwqOf-v5A_CdpgnVfiiMM&r=rEoy_H4r-c4UNUr3jSF-7Q&m=RjntOQpE0PTOmyN9aktQ2Swdw2n9KkMaab5dO_bRoNPQbJdQYV5cBJEfNcJbuuOI&s=rwc-kio_SJHar0SdViNs5UMjP6RG_m8-s8v6at9IV5o&e=%3E> = adds a flag of flag INF-Flag to Segment list administrative flags specified by draft-lin-idr-sr-policy-admin-flags. The value (1) for INF-Flags indicates endpoint node SID is included in installing SID list(s) of the Candidate Path (CP) when set. 3) draft-ali-idr-bgp-ls-sr-policy-sl-opt-distribution-00.txt - send INF-Flag in BGP-LS Why 3 drafts in 1 call? As you can see from the description, if draft-lin-idr-sr-policy-admin-flags is not adopted – then the other two drafts cannot be adopted. Similarly, if draft-liu-idr-sr-segment-list-optimized is not adopted, then draft-ali-idr-bgp-ls-sr-policy-sl-opt-distribution cannot be adopted. Questions for Spring WG: 1) Do these drafts correct implement [draft-ietf-spring-srv6-policy-sid-list-opt] concepts?> 2) Do you see any problem with the adoption of any of these three drafts: (draft-lin-idr-sr-policy-admin-flag-05.txt, draft-liu-idr-sr-segment-list-optimize-06.txt, draft-ali-idr-bgp-ls-sr-policy-sl-opt-distribution-00.txt) Question for IDR: 1) Are there any problems in the technology descriptions? 2) Does the status and setting of this flag work? Are the “delays” inherent in BGP distribution a concern? 3) Does this draft help operators deploy SRv6? Question for Spring and IDR: 1) Does this draft open any error issues? Please include in your comments – Support or No support for adoption. Cheerily, Susan Hares
